Description

Technical Field

[0001] The utility model relates to the technical field of bottle detection, in particular to a phase jump detection device and a compensation unit. Background Art

[0002] Glass bottles are ubiquitous in daily life. During production, transportation, and reprocessing, damage to the bottle mouth, body, and bottom is inevitable. Therefore, before use, the bottle body needs to be inspected for various defects to avoid safety hazards. The applicant's previous patent application, CN202211035377.1, discloses an online bottle microcrack detection device based on high-voltage discharge. The patent's central rotating component is equipped with several crack detection units. Through the cooperation of a screw spacing component and a bottle feed star wheel component, the bottles to be inspected are fed into the crack detection units for microcrack detection. However, if a crack detection unit on the central rotating component of the patent fails and becomes inoperable, if the entire device remains operational, the faulty unit will continue to enter the bottle body, resulting in false detections and missed detections. To avoid false detections and missed detections, the entire detection device must be shut down and the faulty unit must be repaired before it can resume operation. A single faulty detection unit can cause the entire device to cease operation, seriously affecting work efficiency. Utility Model Content

[0003] In order to solve the technical problems in the above-mentioned background technology that when a detection unit fails, the entire device needs to be stopped for maintenance, the faulty unit cannot be skipped, and false detection and missed detection are prone to occur, the utility model provides a phase jump detection device and compensation unit.

[0004] The technical solution of this utility model is as follows:

[0005] A phase jump detection device includes a central rotating component, and a bottle feeding unit and a bottle separating unit are provided on one side of the central rotating component. The bottle separating unit includes a bottle separating star wheel horizontally arranged on one side of the central rotating component and capable of rotating synchronously with the bottle separating star wheel in the opposite direction, and also includes a second motor capable of driving the bottle separating star wheel to rotate. The bottle feeding unit includes a fixed frame arranged on the side of the bottle separating star wheel away from the central rotating component, a screw is laterally provided on the side of the fixed frame opposite to the bottle separating star wheel, and the bottle separating star wheel is arranged near one end of the screw. The end of the screw near the bottle separating star wheel is connected to a first motor capable of driving the screw to rotate. It also includes a control module that can independently control the opening and closing of the first motor and the second motor.

[0006] The bottle feeding unit and the bottle separating unit are controlled independently. When the faulty part on the central rotating component is close to the bottle separating star wheel, the screw only needs to be controlled to stop rotating, and the bottle feeding unit will no longer convey bottles to the bottle separating unit. At this time, no bottles will enter the central rotating component. After the central rotating component rotates for a certain period of time, the control module controls the first motor to start, the screw starts to rotate, and the bottle feeding unit continues to convey bottles. When the central rotating component rotates one circle and the faulty station approaches the bottle separating star wheel again, the control module controls the first motor to stop working again, and the bottle feeding unit stops conveying bottles to the bottle separating unit. This cycle of operation ensures that the faulty part is always in an idle state and no bottles will enter, thereby avoiding false detection and missed detection.

[0007] Specifically, the central rotating component is provided with a plurality of crack detection units on its circumference, and the bottle separation star wheel is provided with bottle separation stations that correspond one to one with the crack detection units, ensuring that the bottle separation star wheel can evenly and accurately deliver bottles into the detection units.

[0008] As a preferred embodiment, an adjustment member is provided on the side of the fixing frame facing away from the screw to adjust the distance between the screw and the bottle-distributing star wheel. As the size of the bottles being inspected changes, the distance between the screw and the bottle-distributing star wheel can be adjusted to accommodate bottles of varying sizes, ensuring that bottles of various sizes can smoothly enter the bottle-distributing star wheel.

[0009] Specifically, the adjustment member includes a push rod positioned perpendicular to the length of the screw, one end of which is connected to the screw via a connector. The fixed frame includes a transverse fixing plate that fits over the outer ring of the push rod and is helically connected to the push rod. The fixing plate is positioned parallel to the screw's rotational axis, while the push rod is positioned perpendicular to the screw's rotational axis. By rotating the push rod, the push rod, through the connector, drives the screw in a linear motion perpendicular to the fixing plate, thereby adjusting the distance between the screw and the bottle-distributing star wheel.

[0010] Furthermore, an adjusting hand wheel is provided at one end of the push rod away from the screw rod, and the rotation of the push rod is achieved by turning the adjusting hand wheel, which can better control the rotation of the push rod and improve the convenience of operation and work efficiency.

[0011] Further preferably, a guide shaft parallel to the push rod is provided between the connecting member and the fixing plate. The provision of the guide shaft not only increases the stability of the connection between the connecting member and the fixing frame, but also provides support and guidance when the screw moves.

[0012] In order to ensure the stability of the screw during movement, at least two guide shafts are provided along the length direction of the screw.

[0013] As a preferred embodiment, a connecting rod is connected between the first motor and the screw, and the ends of the connecting rod are respectively pivotally connected to the first motor and the screw. When the position of the screw changes, the position of the first motor does not need to be changed, while the rotation effect of the screw can still be maintained.

[0014] The present invention also provides a compensation unit for use with the aforementioned phase jump detection device, comprising a photoelectric sensor disposed on one side of the bottle-distributing star wheel and capable of detecting the presence of a bottle on the star wheel. The photoelectric sensor is in communication with a control module, and the control module is capable of controlling the opening and closing of the second motor based on information transmitted by the photoelectric sensor. The photoelectric sensor detects the presence of a bottle on the station corresponding to the fault detection unit on the bottle-distributing star wheel. If a bottle is present, it indicates that a malfunction has occurred in the bottle feed unit while conveying the bottle. At this point, the control module, based on the information transmitted by the photoelectric sensor, controls the second motor to stop operating, the bottle-distributing star wheel and the central rotating component to stop rotating, and the bottle feed unit to undergo maintenance.

[0015] Through the above design, the beneficial effects of the utility model are:

[0016] 1) When a detection unit fails, there is no need to shut down the entire device for maintenance. By controlling the rotation of the screw to limit the bottle conveying, the faulty detection unit can always be skipped, effectively avoiding false detection or missed detection, and ensuring detection accuracy. At the same time, the faulty unit only needs to be repaired when all bottles have been inspected or the detection device is idle, which improves production efficiency.

[0017] 2) By setting the compensation unit, when a failure occurs in the bottle feeding unit and the phase jump program is not completed, the second motor can be promptly controlled to stop moving to prevent the bottle from entering the faulty detection unit. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0024] Example

[0025] Combine Figures 1 to 3 This embodiment first provides a phase jump detection device, which includes a central rotating component 3, and a bottle feeding unit 1 and a bottle separating unit 2 are provided on one side of the central rotating component 3.

[0026] In this embodiment, the bottle separating unit 2 includes a bottle separating star wheel 21 horizontally arranged on one side of the central rotating component 3 and capable of rotating synchronously with the central rotating component 3 in the opposite direction, and also includes a second motor capable of driving the bottle separating star wheel 21 to rotate.

[0027] Specifically, the central rotating component 3 is provided with a plurality of crack detection units circumferentially, and the bottle separation star wheel 21 is provided with bottle separation stations that correspond one to one with the crack detection units, ensuring that the bottle separation star wheel 21 can evenly and accurately deliver bottles into the detection units.

[0028] In this embodiment, the bottle feeding unit 1 includes a fixing frame 11 provided on a side of the bottle separating star wheel 21 away from the central rotating component 3. A screw 12 is laterally provided on a side of the fixing frame 11 opposite to the bottle separating star wheel 21, and the bottle separating star wheel 21 is provided near one end of the screw 12.

[0029] As a preferred embodiment, an adjustment member 14 is provided on the side of the fixing frame 11 facing away from the screw 12, which is capable of adjusting the distance between the screw 12 and the bottle-distributing star wheel 21. When the specifications of the bottles being inspected change, the distance between the screw 12 and the bottle-distributing star wheel 21 can be adjusted to accommodate bottles of different sizes, ensuring that bottles of various sizes can smoothly enter the bottle-distributing star wheel 21.

[0030] Specifically, the adjusting member 14 includes a push rod 141 arranged perpendicular to the length of the screw 12, one end of which is connected to the screw 12 via a connector 15. The fixing frame 11 includes a transversely arranged fixing plate 111, which is sleeved around the outer ring of the push rod 141 and is screwed to the push rod 141. The fixing plate 111 is arranged parallel to the rotation axis of the screw 12, while the push rod 141 is arranged perpendicular to the rotation axis of the screw 12. By rotating the push rod 141, the push rod 141 drives the screw 12 to move linearly in a direction perpendicular to the fixing plate 111 through the connector 15, thereby adjusting the distance between the screw 12 and the bottle-distributing star wheel 21.

[0031] Reference Figure 3 In a specific implementation, the connecting member 15 includes a connecting plate 151 arranged parallel to the fixing plate 111 and located on the side of the fixing plate 111 facing the screw 12. The connecting member 15 also includes linkage members 152 respectively connected to both ends of the screw 12. The upper sides of the two linkage members 152 are sleeved on the outer ring of the screw 12, and the lower sides are respectively fixedly connected to the two ends of the connecting plate 151. The connecting plate 151 is located on the side of the screw 12 away from the bottle-distributing star wheel 21, and does not block the bottles transported by the screw 12.

[0032] Furthermore, an adjusting hand wheel 142 is provided at one end of the push rod 141 away from the screw rod 12 , and the push rod 141 is rotated by rotating the adjusting hand wheel 142 , which can better control the rotation of the push rod 141 and improve the convenience of operation and work efficiency.

[0033] Further preferably, a guide shaft 143 is provided between the connecting member 15 and the fixing plate 111 and is parallel to the push rod 141. The provision of the guide shaft 143 not only increases the stability of the connection between the connecting member 15 and the fixing frame 11, but also provides support and guidance when the screw rod 12 moves.

[0034] To ensure the stability of the screw rod 12 during movement, at least two guide shafts 143 are provided along the length direction of the screw rod 12 .

[0035] In a specific implementation, the push rod 141 corresponds to the middle position of the screw rod 12 , and the two guide shafts 143 correspond to the two ends of the screw rod 12 respectively, and are symmetrically arranged along the rotation axis of the push rod 141 .

[0036] One end of the screw 12 close to the bottle-distributing star wheel 21 is connected to a first motor 13 capable of driving the screw 12 to rotate.

[0037] As a preferred embodiment, refer to Figure 3 A connecting rod 16 is connected between the first motor 13 and the screw 12, and both ends of the connecting rod 16 are pivotally connected to the first motor 13 and the screw 12. When the position of the screw 12 changes, the position of the first motor 13 does not need to be changed, and the rotation effect of the screw 12 can also be guaranteed.

[0038] A phase jump detection device also includes a control module that can independently control the start and stop of the first motor 13 and the second motor.

[0039] The present invention also provides a compensation unit for use with the aforementioned phase jump detection device, comprising a photoelectric sensor 4 disposed on one side of the bottle-distributing star wheel 21 and capable of detecting the presence of a bottle thereon. The photoelectric sensor 4 is in communication with a control module, which is capable of controlling the opening and closing of the second motor based on information transmitted by the photoelectric sensor 4. The photoelectric sensor 4 detects the presence of a bottle at a station on the bottle-distributing star wheel 21 corresponding to the fault detection unit. If a bottle is present, it indicates that a fault has occurred in the bottle-feeding unit 1 while conveying the bottle. At this point, the control module, based on the information transmitted by the photoelectric sensor 4, controls the second motor to stop operating, the bottle-distributing star wheel 21 and the central rotating component 3 to stop rotating, and the bottle-feeding unit 1 to undergo maintenance.

[0040] The working principle of the present invention is as follows: the bottle feeding unit 1 and the bottle separating unit 2 are controlled independently. When a detection unit on the central rotating component 3 fails, the number of the fault detection unit can be automatically / manually input into the control module. When the fault detection unit rotates to a position close to the corresponding bottle separating star wheel 21, the control module controls the screw 12 to stop rotating, and the bottle feeding unit 1 no longer conveys bottles to the bottle separating unit 2. At this time, no bottles will enter the fault detection unit. When the central rotating component 3 rotates to the next detection unit close to the bottle separating star wheel 21, the control module controls the first motor 13 to start, the screw 12 starts to rotate, and the bottle feeding unit 1 continues to convey bottles; when the central rotating component 3 rotates one circle and the fault detection unit approaches the bottle separating star wheel 21 again, the control module controls the first motor 13 to stop working again, and the bottle feeding unit 1 stops conveying bottles to the bottle separating unit 2. This cycle continues until all bottles are detected. During the detection process, the bottle feeding unit 1 always performs a phase jump program on the workstation corresponding to the fault detection unit, so the fault detection unit is always in an idle state and no bottles enter, effectively avoiding false detection and missed detection.

[0041] By independently controlling the bottle feed unit 1 and bottle separation unit 2, when a detection unit fails, there's no need to shut down the entire device for repairs. Instead, the rotation of the screw 12 is controlled to limit bottle delivery, allowing the faulty detection unit to be consistently skipped. This effectively avoids false or missed detections and ensures high detection accuracy. Furthermore, the faulty unit only needs to be repaired after all bottles have been inspected or when the detection device is idle, improving production efficiency. The compensation unit allows the second motor to be promptly stopped if a fault occurs in the bottle feed unit 1 before the phase jump sequence is completed, preventing bottles from entering the faulty detection unit.
